The pop star, a self-confessed workaholic, said the one way she relaxes is by letting her production assistant boyfriend Matthew Rutler take charge in the bedroom.

"The one place I don't need to be in control is in the bedroom," Aguilera said. "I'm a big micromanager. I'm a stickler for organization even when I'm in the studio - so I think every woman should just relax and allow herself to be pleased in the bedroom. It's the one place I can let go, 'You do the work.'"

Aguilera recently showed off her sexy new slimmed-down body in the October issue of Maxim magazine. The singer told Leno her sexuality "comes naturally."

"You know, I'm an artist and I'm expressing myself in a sexual way no matter how that changes throughout the years - It's always been something that comes naturally to me.But at this point in my life, I'm 32, and I feel sexier than ever because you know what you want," she explained.

"It was about appreciating the woman that I've become and being effortlessly sexy - not trying too hard," she added."
